Definitions

  • the present application relates to a vehicle seating layout, and specifically relates to a seating layout that includes hanging seats.
  • Automotive interior design has remained the same for many years.
  • the arrangement includes seats affixed at the bottom to the chassis facing forward (i.e., the direction in which the vehicle will travel).
  • some seats may face sideways or toward the back, but all are affixed to the chassis at their base.
  • FR 2 845 954 A1 discloses a seat articulated to the vehicle floor via couplings in the form of hooks fixed on plates which are integral with a base secured to the floor of the vehicle body.
  • FR 2 725 669 A1 which is regarded as the closest prior art, is directed at a retractable seat having a mobile back supported by connecting rods which are linked at their extremities so as to pivot around transverse axes carried by the seat and by a primary element of the vehicle structure, respectively.
  • the invention is defined by the technical features set forth in independent product claim 1 and method claim 15, with additional features thereof to be found in the dependent claims; disclosed herein are seats configured to attach to the roof of the vehicle, vehicles comprising the same, and methods of using the same.
  • a vehicle seat comprises: a base; a back connected to the base; an arm extending from the base; wherein the arm is configured to attach to a roof rail of a vehicle.
  • a vehicle comprises: a steering column; engine; a roof comprising a rail; and passenger compartment, wherein the passenger compartment comprises the vehicle seat, wherein the arm is attached to the rail.
  • the vehicle seat comprises a base, a back connected to the base, and an arm extending from the base.
  • a method of arranging seating in a vehicle comprises: sliding an arm of the vehicle seat horizontally along a slot in a roof rail and/or crossrail.
  • the vehicle seat comprises a base, a back connected to the base, and an arm extending from the base.
  • Automotive interior space has been very much conventional from its beginning. Automotive interior design has remained the same for many years. Almost all of today's cars use conventional seating arrangement that is two rows of seats which are fixed to the chassis allowing its back to recline forward or backward. In cars, seats are essentially fixed to the chassis at their base and hence there is very limited scope for reconfiguration, e.g., to optimize the space according to the use scenario. For example, with a single passenger, the driver, in the car with a lot of luggage. The driver could be short of space and unable to manipulate the vehicle so as to optimize the available interior space even if he's traveling alone. Additionally, current seating layout in cars does not facilitate sociopetal arrangement.
  • seats are hung from the roof frames of the vehicle.
  • these seats can be slid along the rails.
  • This seating layout offers a wide range of flexibility to the user depending upon the use scenario.
  • a user can change the interior layout according to the situation, thereby allowing greater flexibility within the same interior space.
  • a further option comprises the seats being configured to slide backwards during a frontal impact collision along the rails. During crash of vehicle (frontal impact), sliding of seats backward can minimize the impact, prevent intrusion damage, and enhance the safety aspect.
  • the seat base and/or arm can further comprise safety features that can be actuated to provide stability during an impact.
  • the seat 2 has a base 6 connected to a back 8, with an arm 4 extending from the back 8 and configured to attach the seat 2 to a vehicle roof 30.
  • the seat 2 can be rigid, e.g., with base 6 and back 8 a single unit, or can be flexible, wherein a base hinge 12 connects the base 6 and back 8, enabling the angle of the base to be changed with respect to the back (e.g., pivoted upward against the back 8).
  • a clip, lock, or other mechanism can retain the base 6 in the folded position against the back 8.
  • a back hinge 14 can connect the back 8 and arm 4 such that the back 8 can move with respect to the arm 4.
  • the back hinge 14 can allow a change in angle between the arm 4 and the back 8 to enable reclining or inclining, and/or to allow the seat to pivot around the arm 4.
  • Pivoting of the seat 2 can be accomplished at the connection of the arm 4 to the roof rail 32,36, e.g., using a seat revolving hinge 16 (see also FIG. 2 ).
  • the seat 2 can be configured to pivot around the x axis, and/or to slide along slot(s) 34 to enable sliding along the x axis. Enabling sliding of the seats 2 allows the seats 2 to be gathered together (e.g., stacked; see FIG. 5 ). Similarly, enabling pivoting along the vertical axis (e.g., the y axis) allows rotation, e.g., easy ingress and egress from the vehicle (see FIG. 6 ), and/or social flexibility (e.g., FIG.
  • FIG. 7 an interactive layout is illustrated wherein as a seat can be swiveled around the connection between the arm and the roof, people inside the vehicle can arrange a configuration that facilitates an interactive space environment with ease.
  • main rails extend in an x direction, e.g., from the front to the back of the vehicle.
  • cross rails extend in a y direction, between the sides of the vehicle (e.g., driver's side and passenger's side).
  • the seat base 6 can have base safety feature 18 (see FIG. 1 ).
  • the base safety feature 18 can comprise a braking mechanism that creates friction as the seat moves during an impact to reduce and/or control the speed of the movement, and/or to transfer energy from the seat to the chassis of the vehicle.
  • the base safety feature 18 can provide stability to the seat.
  • the safety features could include an actuation member (e.g., 18) such as cylinder arm, telescopic arm, spring, or a combination comprising at least one of the foregoing.
  • the actuation can be hydraulic, pneumatic, mechanical, or a combination comprising at least one of the foregoing.
  • the actuation member could actuate to engage an anchor fixedly attached to the chassis of the vehicle.
  • the arm safety feature 20, as with the base safety feature 18, can also optionally provide controlled deceleration of the seat during impact, and/or controls the speed of the seat movement, and/or be designed to transfer energy from the seat to the roof rails of the vehicle.
  • the seat belt 32 can be a standard shoulder and lap belt, a harness (e.g., a five-point harness), and/or a convertible seat belt that can be converted from a shoulder and lap belt to a harness.
  • the airbag(s) 22 can, for example, be located in the back 8 and/or base 6 of the seat 2. These airbag(s) can be designed and located to protect passengers seated behind the seat (e.g., in another seat), such as for head protection and/or leg protection, and/or can be designed and located so as to provide energy absorption during a collision for the occupant of the seat.
  • the seats 2 can further optionally include various comfort features, such as arm rests 22, a head rest 10 (which is optionally adjustable), base cushion 26, back cushion 28, supports 30.
  • Possible supports 30 include head supports, shoulder supports, and so forth.
  • the supports 30 can be adjustable to enlarge or narrow the width of the seat back 8 to enable a larger occupant (e.g., an adult or a child's car seat) or smaller occupant (e.g., a child).
  • the back 8 and/or base 6 can be adjustable (e.g., telescoping), thereby enabling them to be adjusted depending upon the size of the occupant. This could even eliminate the need for child car seats, such as booster seats.
  • Embodiment 1 A vehicle seat, comprising: a base; a back connected to the base; an arm extending from the base; wherein the arm is configured to attach to a roof rail of a vehicle.
  • Embodiment 2 The seat of Embodiment 1, wherein the base and the back are connected with a hinge.
